Nice!

How big is the pool of variables it can choose from?

Any insight on why it choose 'region' and 'browserHeight' first?

Ugh, I thought I'd answered this but looks like HN lost my response :-(

Currently it is just: screenWidth/Height, browserWidth/Height, browser, browserVersion, os, referrer, city, region, country.

It picks the variables based on how well they partition the datasets into diverse sub-groups. This is the code that does that job:
